Function
The product is a safe, redundant mechatronic system in accordance with the requirements of EN ISO
13849-1+2. The safe venting pneumatic safety function is guaranteed even in the event of an error in
the valve (e.g. due to wear or contamination). Through its electrical connection (NECA multi-pin plug
socket Sub-D, 9-pin), the product receives secure enable signals (EN1/EN2) from commercially-avail-
able electronic or electromechanical safety relay units, which monitor the machine’s protective
devices (e.g. emergency stop, light curtain, electric door switch on the protective housing, etc.).
